如果直接从图片肝,需要收集足够的图片,然后使用yolo或者pytorch进行训练,得到模型后再进行识别。
 
不过这个人机交互验证码有一个语音验证的功能。
 
只要点击一个耳机的图标,然后就变成了语音识别。
播放一段录音,然后输入几个单词,如果单词对了,那么也可以通过。
 





 
那接下来的问题就简单了,拿到录音->识别录音,转化为文本,然后在输入框输入,就基本大功告成了。
 
英文转文本,网上有不少的AI平台可以白嫖,不过论效果,个人觉得百度的AI效果还不错,起码可以免费调用5W次。
 
完整代码如下:

如果直接从图片肝,需要收集足够的图片,然后使用yolo或者pytorch进行训练,得到模型后再进行识别。
 
不过这个人机交互验证码有一个语音验证的功能。
 
只要点击一个耳机的图标,然后就变成了语音识别。
播放一段录音,然后输入几个单词,如果单词对了,那么也可以通过。
 

xBi84Ow9N6.png

 
那接下来的问题就简单了,拿到录音->识别录音,转化为文本,然后在输入框输入,就基本大功告成了。
 
英文转文本,网上有不少的AI平台可以白嫖,不过论效果,个人觉得百度的AI效果还不错,起码可以免费调用5W次。
